Analyzing Currency Correlations for Beginners: A Comprehensive Guide

Forex trading can be a complex and challenging world to navigate, but one key concept that can help traders better understand the market is currency correlations. Understanding how currency pairs interact and learning to analyze their movements can help traders minimize risk and maximize profit. In this comprehensive guide, we'll cover everything beginners need to know about analyzing currency correlations.

What Are Currency Correlations?

Currency correlation refers to the relationship between two or more currency pairs. Simply put, it's the measure of how those pairs move in relation to each other. This correlation can be positive, negative, or neutral.

Positive correlation means that two currency pairs move in the same direction. When one pair goes up in value, the other also goes up. For example, the AUD/USD and NZD/USD pairs are typically positively correlated.

Negative correlation, on the other hand, means that two currency pairs move in opposite directions. When one pair goes up in value, the other goes down. An example of this is the EUR/USD and USD/CHF pairs, which are typically negatively correlated.

Finally, neutral correlation means that there is no significant relationship between two currency pairs. In other words, their movements are not related. An example of this may occur between the USD/JPY and the AUD/USD.

Why Should Traders Analyze Currency Correlations?

Analyzing currency correlations is an important step for traders as it allows them to assess the potential risk and reward of a particular trade. If a trader is considering opening a long position in one currency pair, they may want to evaluate the correlation with another currency pair to assess the potential impact on their trade.

For example, if a trader is considering opening a long position in the EUR/USD pair, they may want to evaluate the correlation between the USD/JPY pair. A negative correlation suggests that the USD/JPY pair is likely to move in the opposite direction to the EUR/USD pair. Therefore, an increase in USD/JPY may suggest a decrease in EUR/USD, potentially impacting the trader's long position.

Analyzing currency correlations can also help traders better diversify their portfolio. By identifying pairs with low correlation to one another, traders can lessening the risk of holding overconcentrated positions.

Additionally, currency correlations can offer an advantage to traders looking to take advantage of interest rate differentials. By analyzing currency pairs with positive correlation to pairing currencies with interest rate differentials, traders can look to earn on both interest rate and exchange rate changes.

How to Analyze Currency Correlations

There are two primary methods to evaluate currency correlations: utilizing a correlation coefficient or visually by assessing a currency pair correlation matrix.

Correlation Coefficients

The correlation coefficient measures the numerical association between two variables, determining whether they move in the same or opposite directions. The value of the correlation coefficient will range from -1 to +1; -1 being complete negative correlation, +1 being complete positive correlation, and 0 indicating no relationship exists.

There are various ways to calculate correlation coefficients, but the most common method is to use Pearson’s Product-Moment Coefficient Formula:


The closer to the extreme values -1 or +1 the correlation coefficient is, the stronger the correlation. A value closer to 0 indicates a weaker correlation.

Currency Pair Correlation Matrix

An alternative method to evaluate currency correlations is through a currency pair correlation matrix. This matrix displays the correlation coefficient value between each currency pair in a table format, which is easy to read.

Here's a simple example of a currency pair correlation matrix:

AUD/USD 1.000 0.515 0.555 -0.154 -0.738
EUR/USD 0.515 1.000 0.304 -0.801 -0.605
GBP/USD 0.555 0.304 1.000 -0.415 -0.334
USD/JPY -0.154 -0.801 -0.415 1.000 0.313
USD/CHF -0.738 -0.605 -0.334 0.313 1.000

In this example, we see that AUD/USD and EUR/USD have a strong, positive correlation of 0.515. However, the AUD/USD and USD/CHF pairs have a strong, negative correlation of -0.738.

A currency pair correlation matrix allows traders to easily visualize correlations between currency pairs.

Currency Correlation Software

There are also many software options available to traders to help analyze currency correlation coefficients. Here are some popular options:

These tools offer a quick and easy way to assess currency correlations, as the calculations are done automatically.

Currency Correlation Strategies

There are several strategies traders can use once they have identified currency correlations. Here are some of the most popular:

Hedging Against Risk

Hedging is a technique used by traders to lessen the risk of a particular position. Hedging against currency risk is one of the most common uses of currency correlation. Essentially, traders hold both long and short positions in correlated currency pairs, so as one as one pair decreases in value, the other increases, minimizing the overall risk.

Using Currency Correlation to Diversify Portfolios

As mentioned earlier, identifying trading pairs with low correlation can be an effective way to diversify trading portfolios. Having a range of uncorrelated assets allows traders to reduce their overall portfolio risk.

Using Positive Correlations to Take Advantage of Interest Rate Differentials

Another popular use of currency correlation is to exploit interest rate differentials between two countries. Traders will pair currencies with interest rate differentials with a positive correlation in order to take advantage of interest rate and exchange rate changes.

Trading Against Currency Correlations

While most traders use currency correlations to hedge against risks, some traders use them as a potential source of profit. When a pair has a strong positive correlation, one pair’s upward momentum can cause another currency pair to move up in value as well. These correlations can be exploited by traders by pairing strong positive correlations with high volatility in one of the pairs.

Risks of Analyzing Currency Correlations

As with any strategy in forex trading, analyzing currency correlations comes with its risks. As correlations may change over time, traders must continually evaluate and update their portfolio.

Additionally, traders must be wary of unexpected events, such as black swan events, which can send markets into disarray. In such cases, correlations can break down entirely and create unanticipated price movements, which can have a severe impact on traders.

Finally, traders must be aware of the correlation traps. These are pairs that seem to be positively correlated, but in reality, conceal significant downside risks, that can lead to significant losses.


Analyzing currency correlations can be a helpful tool for traders, providing valuable insights into the market’s behavior and significantly reducing portfolio risk. As with any trading strategy, traders must use common sense and be mindful of potential risks. By using the techniques discussed in this comprehensive guide, any beginner trader can effectively leverage currency correlations and take their trading to the next level.
